Abstract

This invention relates to various types of articles mounted with a wireless IC tag (20) with a low magnetic permeability material on a holding part which has first and second surfaces and is made of a high magnetic permeability material. The holding part has a penetrating part which penetrates the first and the second surfaces and a notch which penetrates a part of the continuous first and second surfaces in the periphery of the penetrating part and makes the penetrating part communicate with the outside. A discontinuous region (R) is formed on the holding part in the periphery of the penetrating part due to the notch, and at least on the penetrating part, the wireless IC tag (20) is tightly held together with the low magnetic permeability material. As a result, by providing the penetrating part and the notch, the axis of the reverse direction magnetic flux generated by the eddy current that flows in the periphery of the penetrating part and the notch is shifted from the axis of the magnetic flux produced by electromagnetic waves directed toward the wireless IC tag (20) on the first and the second surfaces, the effects of the magnetic flux due to the eddy current (I) are weakened, and communication with a reader/writer can be performed without troubles.

Description

Fastening products with wireless IC tags

technical field

The present invention relates to fastening products with wireless IC tags, and relates to, for example, sliding fasteners (sliding fasteners), face fasteners (face fasteners), hooks with straps, and rail-shaped fasteners with engaging strips , belt buckle, cord stopper (コードストツパ), belt adjuster (ベルトアジヤヤタタ), swivel (ナス ring, swivel), snap button (スナツプボタン) and other metal-containing fastening products themselves, and covered Daily miscellaneous goods such as quilts and bags, or various high-end brand products such as watches and bags, which contain these fastening products. the

Background technique

In recent years, small and cheap so-called passive wireless IC tags that do not worry about running out of batteries have been attached to products at the production stage, and are used for product management from product production to logistics, sales, etc., to prevent loss, theft and counterfeiting of products prevent etc. the

A passive type wireless IC tag (hereinafter referred to as RFID) is composed of an IC chip, a coil-shaped or coil-shaped antenna, and a coil jumper connecting the two. Most IC chips can store various necessary data, write new data, erase these data, and read new data from the outside. The power supply for the activation of the passive RFID is the so-called electromagnetic induction method (or microwave method) RFID, which does not use a separate power supply, but receives electromagnetic waves received from an external reader/writer (or scanner) (or microwave) generated electromotive force is used as a power source. the

Therefore, the electromagnetic wave transmitted from the reader/writer (or scanner) is not only a carrier wave for transmitting data, but also used as an electromotive force for passive type RFID. The above-mentioned carrier wave is modulated in the reader/writer (or scanner) to a wavelength compatible with the passive RFID, and is received by the receiving antenna of the RFID, and the necessary data stored in the memory of the IC chip is taken out, and the data is used as Response data is modulated to the wavelength corresponding to the reader/writer (or scanner) from the built-in antenna, and the response is transmitted. Alternatively, useless data among the data stored in the memory of the IC chip may be erased according to a command from the reader/writer (or scanner). the

The response transmission signal is received by the receiving antenna of the reader/writer (or scanner), and the response data is analyzed by the control unit of the reader/writer (or scanner). This response data is temporarily stored in the reader/writer (or scanner) as data stored in the above-mentioned passive RFID, and then sent to a control device such as a personal computer. In addition, when data is read from and written into the memory in the above-mentioned passive RFID, various security measures can be taken. the

As a specific example of incorporating such a passive type RFID in a fastening product, for example, there is a "handle for a sliding fastener" described in Japanese Patent Application Laid-Open No. 2002-125721 (Patent Document 1), and described in Japanese Patent Laid-Open 2002 - "Button for Clothes with Sewn Foot Fixation" in Publication No. 42100 (Patent Document 2). the

According to the metal handle of the sliding fastener described in the above-mentioned Patent Document 1, a passive RFID IC chip and a coil antenna enclosed in a thin glass tube are embedded in the main body of the metal handle. Due to the embedding, an embedding hole of the glass tube is formed in the handle main body, and at the same time, a signal transmitting and receiving slit that communicates with the inside and outside and extends in the length direction of the glass tube is formed on the wall of the embedding hole, so that the coil antenna is exposed to the signal transmitting and receiving. By using the slit, it is possible to transmit and receive signals with an external reader/writer (or scanner). After the glass tube enclosing the passive RFID is inserted into the insertion hole, the opening end of the insertion hole is sealed with epoxy resin to prevent the passive RFID from falling off. the

On the other hand, the button for clothing with seams and feet described in the above-mentioned Patent Document 2 is composed of a button body having electromagnetic permeability and a passive RFID attachment body. A circular recess is formed on the surface of the button main body, and a sewing foot that is sewn to clothes or the like protrudes integrally from the back of the button body. the

In the central part of the above-mentioned recessed part, the passive type RFID is coated with an epoxy resin which is a low magnetic permeability material to be integrally fixed. In this passive type RFID, an IC chip and a coil-shaped antenna wound helically around the recess are disposed. After the passive type RFID is arranged in the above-mentioned recessed part, epoxy resin is flowed into the recessed part and solidified to perform sealing and waterproofing treatment. the

Contents of the invention

The problem to be solved by the invention

However, as mentioned above, in the passive type RFID, when the magnetic flux generated by the electromagnetic wave emitted from the reader/writer passes through the coil antenna in the RFID, an induced electromotive force is generated in the coil antenna by electromagnetic induction, and its power becomes RFID power supply. At this time, if a high-permeability material such as metal is placed around the RFID, and the above-mentioned magnetic flux passes through the high-permeability material, an eddy current that cancels the above-mentioned magnetic flux is generated in the high-permeability material. In this way, the attenuation of the magnetic flux causes the decrease of the induced electromotive force. the

This is fatal for passive RFID embedded in metal products. For example, in the handle of the sliding fastener described in the above-mentioned Patent Document 1, a passive type RFID enclosed in a long and thin glass tube is inserted into the insertion hole of the metal handle and sealed with epoxy resin. Also, as mentioned above, the metal around the glass tube generates eddy currents that cancel the magnetic flux generated by the electromagnetic wave emitted from the reader/writer, and the induced electromotive force generated in the coil antenna is greatly reduced. In this patent document 1, the insertion hole is a blind hole with a bottom surface, and although a slit connecting the inside and the outside is formed on the inner wall surface, this slit is just a slit for signal transmission and reception as described in this document 1. . This can also be understood from the fact that a metal tube is arranged on the peripheral surface of the above-mentioned glass tube in a handle made of leather or the like, and a long hole for signal transmission and reception is formed in the metal tube. As a result, in the metal tab, eddy currents are generated around the above-mentioned insertion hole, especially in the metal part at the bottom, and this eddy current cancels the magnetic flux generated by the electromagnetic wave emitted from the reader/writer, making it the induced electromotive force of the RFID power supply. Dropped significantly. the

On the other hand, the above-mentioned Patent Document 2 discloses a buckle in which an IC chip is arranged in the center, a helical antenna is arranged around the buckle to form a passive RFID, and the epoxy resin is cured to seal it. , fixedly integrated in the circular recessed part of the buckle main body. When the button communicates with an external reader/writer (or scanner), the direction of the electromagnetic wave emitted from the reader/writer is emitted toward the center of the button main body. At this time, in Example 2 of this document, the button body is also formed of a synthetic resin material that is a low magnetic permeability material, so there is no problem in particular. However, in the case where the above-mentioned button body is made of metal, as described above , generating an eddy current in the metal part in a direction that cancels the magnetic flux generated by the electromagnetic wave emitted from the reader/writer cannot activate the passive type RFID.

In this way, in the case of attaching a passive RFID to a metal product in the prior art, the present situation is that every effort is made to prevent the above-mentioned influence of the metal product on the coil antenna of the passive RFID. In order not to cause this effect, it is necessary to increase the distance between the metal product and the passive RFID, or to place a shielding material between the metal product and the passive RFID, and take various measures. However, in such countermeasures, not only is it meaningless to adopt a small and inexpensive passive RFID, but it is also impossible to put it into practical use when the product itself is small. the

The above-mentioned eddy current is not limited to occur in the above-mentioned passive type RFID, but may also occur in an active type RFID having a starter battery. Sometimes eddy currents are generated that cancel out magnetic fluxes caused by electromagnetic waves emitted from the reader/writer, attenuating the above electromagnetic waves, and making communication impossible. Therefore, in this specification, RFID includes both passive type and active type. the

The present invention is made in order to solve the problems of the prior art as described above, and its specific purpose is to provide an article with RFID, which eliminates the high magnetic permeability material on which RFID is installed by simple countermeasures. The influence of the electromotive force drop of RFID caused by metal materials. the

The means used to solve the problem

In order to achieve the above object, as the fastening product with wireless IC tag of the present invention, the fastening product with wireless IC tag is provided with a holding part made of a high magnetic permeability material having a first surface and a second surface. Installed with a wireless IC tag installed by a low magnetic permeability material; it is characterized in that: the above-mentioned holding part has a through part that penetrates the above-mentioned first and second surfaces so as to respectively open the above-mentioned first and second surfaces, and is provided with a cutout, the cutout The peripheral part of the above-mentioned penetration part is cut off and penetrates through a part of the above-mentioned first and second surfaces which are continuous around the periphery of the above-mentioned penetration part. The part forms a discontinuous region, and at least in the above-mentioned penetrating part, the above-mentioned wireless IC tag) is held in close contact with the above-mentioned low magnetic permeability material. the

In the present invention, the eddy current that cancels the magnetic flux generated by the electromagnetic wave emitted from the reader/writer flows in the periphery of the above-mentioned through portion and the above-mentioned slit, and the center of the eddy current is shifted from the center of the eddy current held in the through portion. The position where the wireless IC tag leaves. In addition, the above-mentioned wireless IC tag is accommodated inside a housing member formed of a material with low magnetic permeability, and the housing member is composed of a first housing member and a second housing member, and the first housing member and the second housing member are sandwiched by the wireless IC tag for installation. with. the

Typically, the RFID sealed and molded from the low magnetic permeability material is mounted on a fastening product, the fastening product is a sliding fastener, and the holding part of the RFID is a slider and a handle of the sliding fastener. Specifically, it is preferable that the slider has an upper plate, a lower plate, and a connecting column connecting the upper plate and the lower plate, and that the through portion and the cutout are provided at an end edge of the lower plate. In addition, the above-mentioned slider may also have a handle and a handle installation column for installing the handle. The handle installation column includes a front column and a rear column divided in front and rear of the above-mentioned slider, and the above-mentioned through-hole is provided between the opposite end surfaces of the front column and the rear column. portion and above cutout. the

In addition, the fastening product is a sliding fastener, the holding part of the RFID is the handle of the sliding fastening, or the fastening product is a button, and the holding part of the RFID is the main body of the button or the The buttonhole of a button. Specifically, it is preferable that the button has a disc-shaped base and a cover member integrally fixed to the peripheral portion of the base, and the through portion and the cutout are provided on the peripheral portion of the base. Preferably, the above-mentioned RFID IC chip has data for authenticity determination and/or data for physical distribution management. the

On the basis of the above-mentioned structure, it is preferable that the above-mentioned holding part made of a high magnetic permeability material has a shielding member mounting part, and the shielding member mounting part can be connected to an external reader/writer or scanner on the signal receiving and transmitting surface. A shielding member made of a high magnetic permeability material that shields the penetration portion is detachably attached. the

Effect

When embedding and fixing a passive type RFID sealed and molded by a low magnetic permeability material such as epoxy resin, for example, into a holding part made of a high magnetic permeability material such as a metal plate having a first surface and a second surface, usually as already explained, The magnetic flux generated by the electromagnetic wave emitted from the reader/writer passes through the coil antenna in the RFID, and an induced electromotive force is generated in the coil antenna by electromagnetic induction, and its power becomes the power source of the RFID. At this time, if a high-permeability material such as metal is placed around the RFID, and the above-mentioned magnetic flux passes through the high-permeability material, an eddy current that cancels the above-mentioned magnetic flux is generated in the high-permeability material. In this way, the above-mentioned magnetic flux is attenuated, and the above-mentioned induced electromotive force is reduced. the

Therefore, the present inventors have carried out various experiments in order to prevent the generation of the above-mentioned eddy currents. As a result, a penetration portion is formed in the holding portion of the above-mentioned high magnetic permeability material for mounting and holding the RFID, and at the same time, the penetration portion is communicated with the outside. A slit penetrating through the first and second surfaces is formed, and at least a part of the high magnetic permeability material continuously present around the periphery with the center of the RFID antenna mounted on the above penetrating portion as the central axis is formed to communicate with the inside and outside and penetrate the first and second surfaces. The slit is formed to form a discontinuous area of high magnetic permeability material around the above-mentioned penetrating portion. the

It has been known that when an RFID sealed by a material with low magnetic permeability is installed and fixed inside the above-mentioned penetrating portion in which a discontinuous region is formed by a slit in a high magnetic permeability material, when electromagnetic waves are transmitted from a reader/writer, although occasionally There is a high magnetic permeability material except for a part around the RFID, but the signal can be sent and received smoothly and sufficiently between the reader/writer. Here, when RFID is attached, it is housed in a housing member formed of a low magnetic permeability material and sealed. The receiving member is composed of first and second main members each having a receiving recess, and the receiving recess is integrally sealed with the RFID. This is to prevent moisture from adhering to the RFID, or to prevent the RFID from being exposed to high temperatures when the RFID is integrally molded from a low-permeability material in an embedded state. When the above cutout is not formed, it goes without saying that signal transmission and reception cannot be performed at all. the

Therefore, by analyzing the change of the magnetic field when the notch is formed and when the notch is not formed, the direction and position of the current flowing to the surface of the high magnetic permeability material, etc., it is known that when the notch is not formed, the surface of the high magnetic permeability material generates The eddy current flows in one rotation direction with the center of the penetration part as the axis, but by forming the cutout, the eddy current does not occur around the penetration part, but bypasses the penetration part and the cutout along the U-shaped peripheral part of the high magnetic permeability material including the above penetration part and the cutout flow in one direction. That is, by forming the above cutout, the center of the eddy current shifts from the center of the penetration portion toward the surface of the high magnetic permeability material. As a result, the magnetic flux generated by the eddy current also transfers from the penetration portion to the high magnetic permeability material, and the magnetic flux generated by the electromagnetic wave emitted from the reader/writer to the penetration portion acts effectively. the

According to the above configuration, for example, when RFID is installed on the slider, the handle, or the main body and buttonhole of the sliding fastener which is a preferred form of the fastening product, it can be connected with the reader/writer or the scanner. Smooth data communication, such as authenticity judgment and product management, can be performed directly or through a computer. In order to realize this authenticity judgment and product management, it is necessary to store data for authenticity judgment and/or data for physical distribution management in the above-mentioned RFID IC chip. the

However, if, for example, data for authenticity determination and/or data for logistics management are stored, there is a possibility that these data may be analyzed in relation to the final purchaser through the distribution stage, and privacy issues are also included. , On the basis of the above-mentioned structure, it is preferable to set a shielding member installation part on the above-mentioned holding part made of high magnetic permeability material, and the shielding member installation part is on the signal transceiving surface with the external reader/writer or scanner A shielding member made of a high magnetic permeability material that shields the penetration portion is detachably attached. In this case, it is preferable to attach the shielding member to the shielding member attaching portion in a non-detachable manner according to the desire of the purchaser when the product is finally delivered to the purchaser. the

In addition, for the above-mentioned purpose, when there is a holding portion made of a high magnetic permeability material, and an RFID sealed and molded by a low magnetic permeability material is mounted and held on the above-mentioned holding portion, even if an electromagnetic shielding member is installed between the above-mentioned holding portion and the above-mentioned RFID, The electromagnetic shielding member also absorbs electromagnetic waves emitted from the reader/writer, making it possible to prevent eddy currents from being generated in the holding portion made of a high magnetic permeability material. the

Detailed ways

Next, preferred embodiments of the present invention will be specifically described with reference to the drawings. In the following description, an electromagnetic induction type passive RFID is taken as an example, but the RFID of the present invention includes not only electromagnetic induction type but also microwave responding RFID and active type RFID. The articles of the present invention mainly include fastening products and products to which they are attached, but for example, not limited to fastening products, various branded products such as watches and belts are also applicable. the

Examples of fastening products include various fastening products such as slide fasteners, surface fasteners, hooks, rail fasteners, buckles, cord stoppers, belt adjusters, swivels, and snap buttons. For example, various clothes such as bags and sportswear, bags, shoes, and the like can be mentioned as articles on which the above-mentioned fastening product can be covered. the

As a typical form of passive RFID applicable to the present invention, an IC chip has a memory for storing data such as identification information of an object to be identified. The IC chip and the antenna are electrically connected to each other to form a response circuit. As the response circuit, for example, a detection circuit, a power supply circuit, a control circuit, a memory circuit, a modulation circuit, an oscillation circuit, and the like are incorporated. The communication distance of RFID is 0 to less than 10 cm, preferably less than 10 mm. The present invention may also be a contact type IC chip that can communicate when the IC chip is in contact with a reader/writer. the

Next, typical examples of the present invention will be described more specifically. the

Example 1

1 and 2 show half of test pieces 100, 200 of the first embodiment of the present invention and comparative example. As can be understood from these figures, both test pieces 100, 200 have blind holes 101, 201 of the same rectangular parallelepiped shape formed in the central part of one end face of a thick rectangular parallelepiped metal sheet. The lower wall parts 103, 203 of the opposing upper and lower wall parts 102, 103 and 202, 203 are used as passive RFID holding parts, and a through hole for holding a passive RFID not shown in the figure is formed in the central part. 104, 204, the passive RFID has a circular coiled antenna and an IC chip, which are sealed and integrated in a disc shape. the

In the test piece 100 used in the first embodiment of the present invention shown in FIG. A part is cut by the above-mentioned notch part 105, and a discontinuous region R is formed in the metal part. On the other hand, in the comparative example shown in FIG. 2, the above-mentioned notch is not formed, and the metal portion around the through-hole 204 exists continuously, and there is no discontinuous region R like this embodiment. Symbol A shown in FIGS. 1 and 2 indicates the center position of the disc-shaped passive RFID not shown when it is held in the through holes 104 and 204 . the

In addition, in this Example and a comparative example, the passive type RFID (manufactured by Hitachi Maxell) of an electromagnetic induction method (13.56 MHz) was used. In addition, in this example, the test piece which the left-right width of the said notch part 105 was 0.3 mm, 0.5 mm, 0.8 mm, and 2.0 mm was prepared. About these test pieces and the test piece of the said comparative example which did not provide the notch part, the reading test was performed with the pen type reader/writer. As a result, the test piece of the comparative example could not be read at all, but in the test piece of the example, all the test pieces could be read regardless of the size of the left and right width of the notch portion 105 . the

Therefore, the inventors of the present invention performed a simulation test of the eddy current I (vector) around the through-holes 104 , 204 of the respective lower wall portions 103 , 203 for the present example and the comparative example. FIG. 3 shows the position and direction of the current that substantially flows to the through-hole 104 of the lower wall portion 103 of the test piece and the peripheral metal portion of the notch portion 105 of the test piece of this embodiment. 4 shows the position and direction where the current substantially flows on the biaxial plane (wall surface) of the X-Y axis of the current generated in the metal portion around the through hole 104 of the lower wall portion 203 of the test piece of the comparative example. The center of current and measurement is the center of the passive type RFID which becomes point A in FIGS. 1 and 2 . the

As can be understood from these figures, in this embodiment, the cutout 105 is formed so that the current flows in one direction near the periphery of the through hole 104 , the cutout 105 , and the outer peripheral edge of the lower wall 103 . As a result, the axis of the magnetic flux in the opposite direction generated by the eddy current I deviates from the axis of the magnetic flux generated by the electromagnetic wave radiated from the reader/writer on the surface of the lower wall portion 13. In the inner area of the lower wall portion 103 where the source type RFID exits, the density of the induced magnetic flux generated by the electromagnetic wave emitted from the reader/writer does not decrease, nor does the induced electromotive force induced in the antenna decrease. On the other hand, in the comparative example, a large current flows in one direction around the central axis of the passive RFID around the peripheral portion of the through hole 204 of the lower wall portion 203, and a so-called eddy current I is generated. By the generation of this eddy current I, a magnetic flux in the opposite direction to the electrode direction of the magnetic flux generated by the electromagnetic wave emitted from the reader/writer is generated, the above-mentioned magnetic flux density is reduced, and the magnetic flux generated in the antenna of the passive type RFID is reduced. The induced electromotive force also drops. the

FIG. 5 shows changes in magnetic flux density generated in the Z-axis direction at point A in the above-described embodiment and comparative example shown in FIGS. 3 and 4 . In the figure, "•" points indicate the magnetic flux density of the present example, and "×" points indicate the magnetic flux change of the comparative example. The electromagnetic wave having a frequency of 13.56 MHz is introduced into the helical antenna of the passive RFID, so, taking 1/13.56 (second) as the time of one cycle on the horizontal axis, divide it into 16 equal parts to form 16 steps, and draw Magnetic flux density at each step. It can be seen from this figure that the magnetic flux density of the present embodiment has a magnitude approximately 9 times that of the comparative example at each step. This truly shows how the present invention can prevent the occurrence of the above-mentioned eddy current I, and shows how the drop in induced electromotive force that occurs in passive RFID is eliminated compared with the prior art. the

Like this according to the present invention, in the high magnetic permeability material of the passive type RFID of mounting and holding electromagnetic induction mode, the notch portion that communicates inside and outside penetrates from the first surface to the second surface, forms the discontinuous area of high magnetic permeability material, only by With such a simple process, it is possible to obtain a level of responsiveness that cannot be predicted in the conventional response performance with the reader/writer. Also in the following second to sixth embodiments, smooth responsiveness to an unpredictable degree in the response performance with the reader/writer is obtained similarly to the above-mentioned first embodiment. Therefore, with regard to the second to sixth embodiments, the description related to the responsiveness thereof is limited to the result of the description. In addition, the frequency of the electromagnetic wave emitted from the reader/writer applicable to the passive RFID of the electromagnetic induction method in the present invention is not limited to the above-mentioned 13.56 MHz, for example, it may be a frequency in the 2.45 GHz band, or other frequency. Also, the width dimension of the notch portion 105 can be changed in various ways, and it is preferable to set it to a value as large as possible, but this value is not uniform, and it is preferable to select an appropriate value through experiments or the like. the
